IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 55,360, dated June 5,1866.

To all whom t 'may concern.-

Be it known that I, S. T. W. POTTER, of Scott, in the county of Cortlandand State of N ew York, have invented a new and Improved Ohurn; and I dohereby declare that the following is a tull, clear, and exactdescription thereof', which will enable others skilled in the art tomake and use the saine, reference being had to the accomlianyingdrawings, forming part of this specification, in which- Figure l isavertical section of' a churn-box having my improvements applied thereto,taken on the plane of the linear x, Fig. 3. Fig.l 2 is a transversesection taken ou the plane of the line y y, Fig. l. Fig. 3 is a planview ot' the device with a lid thrown back, the operating mechanismhaving been removed, the plane of section taken ou the line Z Z, Fig. 1.

Similar letters ot reference indicate like parts.

My invention consists in a novel construction of the dashers employedfor agitating the cream in a churn for producing butter.

A designates the body of the churn, which is a quadrangular box ot' anyappropriate size.

l From opposite sides ot` the churn-body there arise two standards, B B,secured together at the top by a cross-piece, a.

O is a double crank-shaft journaled in the standards B. Two cranks, b b,extend in opposite directions from the shatt O, each crank carrying apitman, D, connected to thedasherrods,t'or imparting alternateup-and-down motion to the dashers. The crank carries on one end agear-wheel, c, which is operated by a larger gear-wheel, d, which lattercarries a winch, c. The other end ofthe shaft carries a y-wheel,f.

The special novelty of this churn consists in the construction andarrangement of the dashers. To the lower end ot' each dasher-rod o thereis secured a longitudinal strip or arm, E, having a convex or roundingface. The object of having' the face rounding is to throw the cream fromthe sides of the churn to the center.

F F are the loats of the dashers. Those on the one arm are so arrangedrelatively with those on the other arm that they will pass eachotherthat is, they are alternate. This will be understood by referenceto Fig. 3.

To the dasher-rod g, above the arm E, there is secured a strip, G, thestrip on the one rod being carried round Iacross one end of themachineand the strip on theother around the other end ot' the machine. Thesestrips I term scrapers because ofthe otlice they performthat is, theyact as scrapers for scraping the cream from the sides of the churn andthrowing it down into the body of the churn to be acted upon by thedashers. The dasher-rods are guided in their course in any suitablemanner.

The lid of the churn is made in two parts, each ot' which is providedwith a glass, n, Fig. 3, for enabling a person to see inside the churnwithout opening the lid.

The dashers and scrapers operate efficiently upon the cream; and bytheir use l 'am enabled to produce a large quantity of butter from agiven quantity of cream in a shortI space of time.

What l claim as new, and desire to secure by Letters Patent, is-

l. The Heats F, secured to the dasher-rods g, constructed and arrangedsubstantially as described.l

The scrapers G, in combination with the tloa-ts F, substantially asshown and described.
